I thought the luau themed #10 balloon mosaic was my favorite but I really love how this number 3 turned out. 
I used black foam boards this time and it went great with the hot pink, black & white, zebra theme. 



Print template and arrange pages. See preview window while printing to make sure the layout is the same. Some printers are different. Pages could be vertical and 5 across.

Starting in the center helps keep everything straight. Tape pages together and cut out.

Foam boards purchased online from Dollar Tree (affiliate link)

They sell them in packs of 25. I have purchased in store but the stock is sometimes out.


6 boards per most numbers. The #1 only takes 4 boards. 

Tape 3 boards together and tape the template down and trace.

Use a box cutter or exacto knife to cut from the foam board.
I'm using these from Amazon since you can just pop the end off and have a brand new blade.

Measure 6" wide template for the side pieces.

Trace the template to make 3 side pieces per boards.

Here are 2 boards cut making six side pieces. You will need approximately nine side pieces per number. (except #1 will use less)

For rounded edges lightly score the foam board about 1" sections. Be careful not to press too hard.

Gently press the foam board to open the scored lines. 

I use a regular hot glue gun to attach sides. 

Because the sides are 6" wide it stands pretty well. If you are going to use it outdoors you might want to add a stand. The last couple photos on my USA post show stands with weights to hold them in place. They were outside all day long and never moved. 

I purchased the balloons from Amazon

I used the leftover pink balloons from the Luau themed 10th balloon mosics.

The zebra and party print pink balloons came from a set. I decided not to use the mylar balloons.

I started using a low temp glue gun to attach balloons and I like it so much better. The balloons do not move. It does take a bit of time to wait for each one to dry and you have to watch out for glue strings. 


I've shared templates with hundreds of people and look at all this creativity!!!! So happy and they all turned out amazing!!! Thank you for sharing.
